That's a Fuze+, so this is in the wrong forum. Perhaps one of the moderators will move it.

I don't have a Fuze+, but I do have some other Sansa players, so these answers are probably true....

drag & drop...yes

play from folders...yes...look for Music...folder (it's probably at the bottom of the Music section

playlists on the micro SD card...I do it on the Clip, Clip+, and Fuze, so I'll guess that you can do it on the Fuze+. However, lots of people have issues with making playlists, so it's best to do some reading in the Fuze+ section.
